Presentation transcript:

FLEXIBLE SIGMOIDOSCOPY SAN ANTONIO Flexible Sigmoidoscopy San Antonio is the visual examination of the inside of the rectum and sigmoid colon, using a lighted, flexible tube connected to an eyepiece or video screen for viewing. This device is called an endoscope. The colon (large intestine) is 5 to 6 feet long. During a sigmoidoscopy, only the last 1 to 2 feet of the colon is examined. This last part of the colon, just above the rectum, is called the sigmoid colon.

Equipment for Sigmoidoscopy San Antonio The flexible endoscope is a remarkable piece of equipment that can be directed and moved around the bends in the lower colon and rectum. The image in the bowel is transmitted through the endoscope either to the eyepiece or a video screen. An open channel in the scope allows other instruments to be passed through it to take tissue samples (biopsies) or to remove polyps.

The Procedure Flexible Sigmoidoscopy San Antonio is usually performed on an outpatient basis. It is performed with the patient lying on the left side with the legs drawn up. A sheet is placed over the lower body. A finger or digital exam of the anus and rectum is performed. Then the endoscope is gently inserted into the rectum. Air is inflated into the bowel to expand it and allow for careful examination. The patient usually feels a slight discomfort similar to strong gas cramps. The endoscope is then advanced under direct vision and moved around the various bends in the lower bowel. It is advanced as far as possible without causing undue discomfort. When possible, the exam is continued to 25 inches (60 cm). Certain conditions, such as diverticulosis, irritable bowel syndrome, or prior pelvic surgery may produce discomfort when the sigmoid colon is entered by the endoscope. The exam is stopped if this occurs. The exam usually takes 5 to 15 minutes. Sedation is not normally required. Benefits The benefits of sigmoidoscopy can include the following:  It is often possible to determine the specific cause of symptoms.  Conditions such as colitis and diverticulosis can be monitored to determine effectiveness of treatment.  Polyps and tumors can be discovered at an early stage.

Preparation for the Test To obtain the full benefit of the exam and allow a thorough inspection, the rectum and sigmoid colon must be clean. Preparation usually involves drinking clear liquids the day before along with taking enemas and/or laxatives. Specific instructions for preparation are provided beforehand.
